摘要： A vehicle includes a system and method of operating a gearbox of the vehicle. The vehicle includes an interface for entering a desired vehicle acceleration and a processor. The system includes a processor. The processor is configured to receive the desired vehicle acceleration, create an objective function that relates the desired vehicle acceleration to a torque, perform an optimization process on the objective function to determine the torque, and apply the torque to the vehicle to achieve the desired vehicle acceleration.

摘要： A vehicle includes a control system that performs method of operating the vehicle. The control system includes a first motor processor associated with a first motor of the vehicle. The first motor processor receives a torque command from a vehicle motion control module, coordinates an allocation of the torque command into a first motor torque at the first motor and a transmission torque at a first transmission associated with the first motor, and controls the first motor to apply the torque command at the first motor.

摘要： A system for controlling a transmission state of a vehicle includes a controller connected to a first drive system and a first transmission including a gear system, a first clutch and a second clutch. The controller is configured to receive a request to change from an initial transmission state to a target transmission state when a propulsion torque is applied to the vehicle. The controller is configured to distribute the propulsion torque such that all of the propulsion torque is applied by a second drive system and the first drive system does not provide any propulsion torque to the vehicle, fully release an off-going clutch from the gear system, control a motor speed based on a rotational speed relation of the target transmission state to reduce a slip speed of the on-going clutch, and fully engage an on-coming clutch to put the first drive system in the target transmission state.

摘要： An electric vehicle, a system and a method of operating the electric vehicle. The system includes a first motor, a drive unit between the first motor and a first axle of the electric vehicle, a second motor, and a processor. The processor is configured to receive a request for the electric vehicle, receive a torque signal from the drive unit, determine at least one of a first motor torque for the first motor and a second motor torque for the second motor based on the torque signal and the request, and apply the at least one of the first motor torque at the first motor and the second motor torque at the second motor to satisfy the request.

摘要： A system and method for operating an electric vehicle. In another exemplary embodiment, a system for operating an electric vehicle is disclosed. The system includes a first motor and a transmission coupled to the first motor. The transmission is configured to shift gears when a speed of the electric vehicle crosses a shift threshold. The shift threshold is independent of a position of an acceleration pedal of the electrical vehicle.
